Are we really that insecure? Maybe so, but Tori, if you know that she is trans, then I am assuming that she is out. If she is out, then going to her for help is exactly what you should do. If she is not, then be a friend - the opportunity to talk and to learn from each other will happen both naturally and quickly.
When I was first getting to know Julie, I would have given anything to have someone else to talk to, share a meal with, to learn from. I didn't and so blundered about seemingly forever. I don't blunder as much any more, I have friends in both cyberspace and real space. I would not trade anything for any of them.
Peace,
Julie
